Putting one step ahead of Albert Einstein The Nobel Prize in Physics 2022 was awarded jointly to Alain Aspect, John F. Clauser and Anton Zeilinger “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science.” Alain Aspect was born in 1947 in Agen, France. Ph.D. 1983 from Paris-Sud University, Orsay, France. Professor at Université Paris-Saclay and ÉcolePolytechnique Palaiseau France. Alain developed a setup to close an important loophole. He was able to switch the measurement settings after an entangled pair had left its source, so the original setting that existed when they were emitted could not affect the result. John F. Clauser was born in 1942 in Pasadena, CA, USA. Ph.D. 1969 from Columbia University, New York, USA. Research Physicist, J.F. Clauser& Assoc., Walnut Creek, CA, USA. John Clauser built an apparatus that emitted two entangled photons at a time, each towards a filter that tested their polarizati...

This meant she had to travel two and a half hours every day by the local train, so that she could make it in time for training at 8am on the Vivekananda Ground in Kolkata. Easier said than done, she woke up at 4.15 everyday so that she could board the local which left Chakdah at 5.05 sharp, and reached a small local station in the big city in Kolkata. A...
